UA Fighting Style features/Options.

I want to make a strength based unarmed Fighter, and found the (UA) Unarmed fighting style that was released last winter.

but i Can't find it on DnD beyond?
Is it not an official rule? or is it not released to Dnd Beyond yet?

I found an old update from DnD beyond that said that they were working on it, but that was more than 6 months ago?

Any idéas how i can homebrew it on dnd Beyond??

They’re still working on it. The coding required to make Class Variants work was a massive undertaking. You can track the progress here:
